Lab Exercise 10: Steganography Goal:The goal is to understand how a photo can hide directly in "plain sight". Hi eAPhotoBegin by finding a photo on the WWW. Think of a topic, do a search, check under Images, and select a photo that is (a) less than 700 x 474 in size, (b) is interesting, (c) suitable for classroom display. You should not spend more than 10 minutes on this. I will use the photo at right, which is 400x400. Grab the "Hide" code that comes with this lab. Edit it to (a) change the integer wid to be the width of your photo (400), integer hi to be the height of your photo (400), and loadImage( ) command to reference your .jpg file, loadImage("mine.jpg"). Run the program, being sure your picture and the fog picture (also given with the lab) are in the data folder, click the mouse, and notice that you now have a labFog.png file. This is the fog picture with your photo hidden inside of it. RevealAPhotoThe following Processing code extracts a photo hidden in the last two bits of the pixels of a .png photo. Type this code as a new Processing program, commenting each line. Understanding the purpose of each line of this code is the point of this assignment. As you enter it, adjust the wid and hi parameters to match your photo. PImage fog; int flip = 0; int srcw=700; // width of the source (fog) photo int srch=474; // height of the source (fog) photo int wid=400; int hi=400; color c, cprime; void setup( ) { size(srcw, srch); fog = loadImage("labFog.png"); image(fog,0,0); } CSE120: Computer Science: Principles
